A global renaissance wave for the use of green hydrogen, an alternative fuel produced using clean energy, is taking place. The green hydrogen has already been rallied as one of the alternatives that can help in bringing down emissions in the world to zero by the next few decades.
Green energy was initially introduced in the United States of America during President George W. Bush’s first administration and was nicknamed the “freedom fuel.” With the new President of the States, Joe Biden, having the use of green energy and net-zero emissions as one of the policies he signed on assuming power, he has promised to bring back the green hydrogen. In the next decade, the Biden administration promises the citizens to be able to access green hydrogen at the same cost as conventional hydrogen as part of its global warming reduction plans. Other countries globally including, Chile, Japan, Saudi Arabia, Germany, and Australia, have already made a significant investment into green hydrogen.
According to experts’ statement to ABC, the green hydrogen market is expected to experience a boom in the next ten years. Green hydrogen is attributed to possessing numerous uses, especially at this time when governments are trying to de-carbonize the energy and industrial sectors. This is according to Randy Bell, who is the director at the Global Energy Center at the Atlantic Council.
The cleanliness of hydrogen very much relies on the production process. Gray hydrogen, which is the common type of hydrogen in the market know, is produced by exploiting fossil fuels, emitting carbon dioxide. “Blue” hydrogen is produced by the use of natural gas and recycling the carbon dioxide discharges hence making it cleaner than the gray one. However, green hydrogen is synthesized by splitting hydrogen and oxygen molecules in water using electricity, and the byproduct of the process after hydrogen combustion is water.
With solar and wind energy not expected to effectively provide the energy needed for heavy productions, long-distance transport like tracking and cargo ships, green hydrogen is expected to supplement that need primarily due to its high energy density. For instance, batteries are known to be bulky and heavy, which poses a problem especially for air travel and does not work the same way as fuel, which is bulky too but burns as it is used in flights. Hydrogen is also better placed in terms of long-term storage, unlike batteries, which makes it a better choice. Another advantage of hydrogen is its ability to produce high-quality heat that can be used in steel mills and fuel for ships.https://industribune.net/
